Above are plots of Electrical Conductivity (EC) (left) and HPT pressure (right) collected concurrently while the probe is advanced at a site in Salina, KS. Both the HPT pressure and the EC data confirm that clays predominate the upper 20 feet, which is underlain by ~35 ft. of silts and sands, followed by 10 ft. of clays. Static water level was calculated to be at 31 ft. The HPT log was made to characterize potential contaminant migration pathways at the site. The line drawn on the HPT pressure plot shows the hydrostatic increase as the probe gets deeper below the static water level.
